Three steps to calmer eyes.

It watches the clock

Lumora runs quietly in the background, counting down your work interval — 20 minutes by default (the 20-20-20 rule). You don't think about it until it's time.

🌙

Your screen gently dims

When it's time, your screen fades to a calming dark overlay over 2 seconds — no jarring popups. A breathing animation and countdown guide you through the break.

🌿

You breathe and return

Follow the 4-4-4 breathing cycle (inhale, hold, exhale) for 30 seconds. When it's over, the overlay fades away and you're back — refreshed and focused.

Everything you need. Nothing that distracts.

Built for people who spend long hours at screens and want a break reminder that actually feels good.

🫧

Guided Breathing

4-4-4 breathing cycle (inhale, hold, exhale) with visual animation. Two themes: Generative Particles or Breathing Orb.

🎨

Frosted Lavender Design

Glassmorphism UI with soft lavender gradients, frosted glass panels, and Apple-grade typography. Feels like a wellness app, not a tech tool.

⚙️

Flexible Presets

Light (30 min), Standard (20 min), or Intense (10 min) — or set custom work and break durations down to the second.

🧠

Smart Detection

Automatically postpones breaks during fullscreen video, presentations, and video calls. Never interrupts when it shouldn't.

🔔

Soft Chime

Optional gentle sound at break start and end. Subtle enough to not startle — just a whisper that it's time.

📊

Streak Tracking

Daily break count, skip count, total break time, day streaks, and a weekly activity chart — all in a beautiful glass dashboard.

Snooze & Skip

Not the right moment? Snooze for 5 minutes or skip entirely. Take a break early with one tap from the popup.

🌀

Two Visual Themes

Choose between floating generative particles or a mesmerising breathing orb for your break overlay. Both animate with your breath.

🪶

Lightweight

No background network calls, no heavy dependencies. Uses Chrome alarms and idle APIs — near-zero impact on performance.

Designed to feel like calm

Lumora uses a Frosted Lavender glassmorphism design inspired by Apple Health and iOS Weather. Every surface is a frosted glass panel on a soft lavender gradient — because a wellness tool should look like one.

Common questions.

Every 20 minutes, look at something 20 feet away for 20 seconds. It's recommended by eye doctors to reduce digital eye strain. Lumora automates this by dimming your screen and guiding you through a breathing exercise.
Yes! Lumora works on both Chrome and Edge. Both browsers support Manifest V3 extensions — just install from the respective store.
Not if you enable Smart Detection. It automatically detects fullscreen mode (video calls, YouTube, presentations) and postpones the break. After 3 retries, it sends a gentle notification instead of dimming.
Yes. Choose a preset (Light: 30 min work / 30 sec break, Standard: 20 min / 30 sec, Intense: 10 min / 20 sec) or set custom durations. Work time: 1–60 minutes. Break time: 10 seconds to 5 minutes.
